Lithium–sulfur battery
| Specific energy | 350 Wh/kg[1] |
|---|---|
| Energy density | 350 Wh/l |
| Charge/discharge efficiency | C/5 nominal; up to 2C |
| Nominal cell voltage | often packaged for 3 Volts, cell voltage in range 2.5-1.7. |
The lithium sulfur battery (Li-S battery) is a rechargeable galvanic cell with a high energy density.[2] The chemical reactions are analogous to those in those in the sodium-sulfur battery. By virtue of the low atomic weight of lithium, Li-S batteries are light-weight. They have been demonstrated on solar powered airplanes.[3]
